WattCycle 12V 314Ah Mini Super LiFePO4 baterija s Bluetooth & Active Balance | ECE R10 certifikat

Yes. The WattCycle 12V 314Ah Mini Super LiFePO4 battery features a Bluetooth interface with password protection, allowing you to monitor the battery status and manage additional functions.

Using the WattCycle app, you can monitor the following data (for reference only; actual data may vary depending on the app version): status, temperature, voltage, current, and individual cell voltages.
You can also control the charging and discharging processes of the battery directly via the app.

Two 12V 314Ah Mini LiFePO4 batteries connected in parallel and one 12V 628Ah Ultra LiFePO4 battery provide the same total capacity. However, using a single battery system generally offers better consistency and more stable operation. In addition, it requires less wiring and takes up less installation space. To conclude, one 12V 628Ah battery is more recommended.

Yes! LiFePO4 batteries are among the most stable lithium batteries on the market. WattCycle LiFePO4 batteries use high-quality Grade-A LiFePO4 cells and are equipped with an integrated battery management system (BMS) that provides protection against overload, overvoltage, extreme temperatures (including deep discharge protection), and much more. All WattCycle batteries undergo rigorous testing before shipment and have certifications such as CE, RoHS, and UN38.3. Buy with confidence now!

The WattCycle 12V 314Ah Mini Super LiFePO4 battery measures 386.5 × 206.3 × 272.8 mm (L × W × H) and weighs 27.23 kg. It is 40% more compact and 66% lighter than three conventional 12V 100Ah AGM batteries.

An active balancer is a cell management technology that actively redistributes charge from cells with a higher state of charge (SoC) to those with a lower SoC during operation, rather than dissipating the voltage difference as heat. Its purpose is to maintain a consistent charge level across all cells and ensure that no cell significantly leads or lags at any point during charging or discharging.

At system level, the Battery Management System (BMS) continuously monitors the voltage of each individual cell and, when deviations are detected, transfers energy bidirectionally between cells. This is an ongoing, real-time process rather than a one-off correction, keeping all cells within a tight and consistent voltage range.

For the user, the active balancer operates entirely in the background. It requires no manual configuration, no scheduled maintenance, and no intervention under normal operating conditions. Cell balancing is managed automatically from the moment the battery is put into service.

The WattCycle 12V 314Ah Mini Super LiFePO4 battery is equipped with a 3A active balancer. This capacity is sufficient to correct significant imbalances not only during idle periods, but also throughout active charge and discharge cycles—where cell deviations tend to develop most rapidly in real-world use.

If the balancing switch is on, balancing will begin when the maximum cell voltage differential in the battery pack exceeds this value and will end when it falls below this value.

For example, if you set the balancing start voltage differential to 10mv and the balancing stop voltage differential to 5mV, balancing will begin when the cell voltage differential exceeds 10mV and end when it falls below 5mV.

The recommended balancing start voltage differential is 0.005V for cells over 50Ah, and 0.01V for cells under 50Ah.

When the lowest cell voltage is below the set value of 2000mV, active balancing will not begin, even if the cell voltage differential exceeds the set value. The balancing current represents the continuous current used to discharge the high-voltage battery and charge the low-voltage battery during energy transfer. The maximum balancing current represents the maximum current during energy transfer, which does not exceed 3A.

Active balancing is a cell management technique that moves charge from higher-voltage cells to lower-voltage cells, keeping every cell in the pack at a similar state of charge instead of simply shedding excess energy as heat. So your battery won't get hot as soon as you start using it, like before.

At a continuous 3A rate, this balancing is strong enough to correct cell drift during normal use and to support higher, safer charge currents.

Practically, active balancing means you retain more usable capacity over the life of the battery pack, accept faster and fuller charging without hitting early cutoffs, and experience slower capacity fade so the system delivers steady performance year after year.

Without active balancing, individual cells drift to different States of Charge (SoC) over repeated cycles, which means the battery’s usable energy is effectively capped by the weakest cell; that mismatch forces earlier charge or discharge cutoffs, limits safe charge rates, reduces usable capacity, and accelerates overall ageing.

The active balancing function is activated only under the following conditions:

• During charging: when the charging current is below 47.1 A.
  
• At rest (idle state): when the voltage of each of the four cells is ≥ 3.2 V, and the voltage difference between the cells exceeds 15 mV.

The difference between 1A, 2A, and 3A active balance lies in the maximum current (amperage) they can use to transfer energy between battery cells.

In essence, a higher amperage rating means the active balancer can correct imbalances more quickly and handle larger cell capacities more effectively. All types use non-dissipative energy transfer methods, meaning they are more efficient and generate less heat compared to passive balancing systems.

The WattCycle 12V 314Ah Mini Super LiFePO4 Battery is very powerful and suitable for most common inverters.

• Continuous power: It can deliver 2560W of continuous power. This is enough to continuously operate most camping and household appliances, such as kettles (1000-1500W), coffee makers, or even small air conditioners.
• Peak power: Thanks to our powerful 200A BMS, it supports a peak power of up to 5632W (220A for 10 seconds). This provides ample reserves to easily start devices with high starting currents, such as microwaves or refrigerators/compressors.

In short, the 12V 314Ah Mini Super LiFePO4 Battery is ideal for inverters up to approximately 2500W-3000W in continuous operation and can also handle larger loads for short periods.

No, the 12V 314Ah Super Lithium Battery cannot start a car. However, it can be used as an auxiliary battery for cars.

The battery should be stored at a state of charge (SoC) between 40% and 60%. Recharge it every three months to maintain optimal condition.The recommended storage temperature is between -10°C and 40°C.Avoid storing the battery fully charged or completely discharged, as this may affect its performance and lifespan.

Yes. The LiFePO4 12V 314Ah Mini Super battery supports an operating temperature range of -20°C to 70°C.At temperatures below -20°C, the battery will automatically stop discharging to protect itself. Once the temperature rises above 5°C, the BMS protection is lifted, and the battery resumes normal operation.This ensures safe and reliable performance even in low-temperature environments.

Yes. The housing of the WattCycle LiFePO4 12V 314Ah Mini Super battery is removable.

However, please note: If you make any unauthorised modifications to the internal structure of the battery without consulting customer service, and this leads to an incident, WattCycle will accept no liability, and the warranty will be void.
